Coinfection with virus alters Phomopsis subordinariaperformance
We investigated the effect of PlLV coinfection on P. subordinariawithin-host infection load (measured as AUDPS), and transmission potential (measured as pycnidia density) in an inoculation experiment with two P. subordinaria strains (P29 and P43). The two strains differed significantly in their AUDPS with strain P43 outperforming strain P29 (Table 1; Fig 2B). For both strains, within-host infection load (measured as AUDPS) was lower under coinfection with PlLV than whenP. subordinaria infected the host alone (Table 1; Figs. 2AB). Pycnidia density was significantly higher under coinfection than under single infection, while P. subordinaria strains did not differ in their pycnidia densities (Table 1; Fig. 2C).
